Fig. 7From: Auxin efflux carrier ZmPIN1a modulates auxin reallocation involved in nitrate-mediated root formationIAA fluxes and contents in PR tip and LRP initiation zone of ZmPIN1a-OE plants. A-B Mean IAA efflux in PR tip (A) and mean IAA influx in LRP initiation zone (B) of WT and ZmPIN1a-OE plants at 2 d after LN and NN treatments. C-D IAA content in PR tip (C) and LRP initiation zone (D) of WT and ZmPIN1a-OE plants at 2 d after LN and NN treatments. Values with error bars represent mean ± SD (n = 3). Different letters indicated a significant difference between different treatments calculated by Fisher's LSD (P ≤ 0.05)Back to article page
